I know this comment will probably ensure I get on some kind of "list", but you don't need the laptop itself to be the fuel. It could be an accelerant or fuse, packed between fuel in a large bag, and multiple bags sent. Yes, putting laptops in the hold it is an improvement, assuming your attack vector is intentionally placed small explosives. Randomly placed large explosives, or large explosives placed intentionally by an insider, might be as effective or more so. But I know jack shit about the design of airplanes so I have no idea if this is the case.
